You have two biased coins. coin a comes up heads with probability 1 / 4. coin b comes up heads with probability 3 / 4. however, you are not sure which is which, so you choose a coin randomly and you flip it. if the flip is heads, you guess that the flipped coin is b; otherwise, you guess that the flipped coin is a. a) True b) False

Answers

False. To get an accurate answer, you should flip the coin at least 4 times.

The sycamore grove contains 30 sycamoretrees. That's 75 percent of all the sycamore
trees in the park. How many sycamore trees
are in the park?

Answers

Answer:

40 sycamore trees

Step-by-step explanation:

We can use the following equation to calculate the total number of sycamore trees in the park:

75% of Total sycamore tree = 30 sycamore tree

0.75 of Total sycamore tree = 30 sycamore tree

$\textsf{ Total sycamore tree = $\sf (30)/(0.75) $ sycamore tree}$

$\textsf{ Total sycamore tree = $\sf 40 $ sycamore tree}$

Therefore, there are 40 sycamore trees in the park.

Let’s assume that the number of sycamore trees in the park is x. According to the problem statement, 30 sycamore trees make up 75% of all sycamore trees in the park. This can be expressed as:

30 = 0.75 * x

Solving for x, we get:

x = 30 / 0.75

x = 40

Therefore, there are 40 sycamore trees in the park.
